    Configuring LAN Ports for Layer 2 Switching, page 10

    Assigning IP Addresses to Switch Virtual InterfacesTo configure IP routing, you need to assign IP addresses to Layer 3 network interfaces. This enables communication with the hosts on those interfaces that use IP. IP routing is disabled by default, and no IP addresses are assigned to Switch Virtual Interfaces (SVIs).

    An IP address identifies a destination for IP packets. Some IP addresses are reserved for special uses and cannot be used for host, subnet, or network addresses. RFC 1166, Internet Numbers, contains the official description of these IP addresses.

    An interface can have one primary IP address. A a subnet mask identifies the bits that denote the network number in an IP address.

    Beginning in privileged EXEC mode, follow these steps to assign an IP address and a network mask to an SVI

    Command Purpose

    Step 1 configure terminal Enter global configuration mode.

    Step 2 interface vlan vlan_id Enter interface configuration mode, and specify the Layer 3 VLAN to configure.

    Step 3 ip address ip-address subnet-mask Configure the IP address and IP subnet mask.

    Step 4 end Return to privileged EXEC mode.

    IEEE 802.1x ProtocolThe IEEE 802.1x standard defines a client/server-based access control and authentication protocol that prevents clients from connecting to a LAN through publicly accessible ports unless they are authenticated. The authentication server authenticates each client connected to a port before making available any services offered by the router or the LAN.

    Until the client is authenticated, IEEE 802.1x access control allows only Extensible Authentication Protocol over LAN (EAPOL), Cisco Discovery Protocol (CDP), and Spanning Tree Protocol (STP) traffic through the port to which the client is connected. After authentication, normal traffic can pass through the port. See Configuring IEEE 802.1X Port-Based Authentication chapter in the Cisco 7600 Series Router Software Configuration Guide, Cisco IOS Release 15S.

    IGMP Snooping for IPv4IGMP snooping allows switches to examine IGMP packets and make forwarding decisions based on their content. You can configure the switch to use IGMP snooping in subnets that receive IGMP queries from either IGMP or the IGMP snooping querier. IGMP snooping constrains IPv4 multicast traffic at Layer 2 by configuring Layer 2 LAN ports dynamically to forward IPv4 multicast traffic only to those ports that want to receive it.

    Layer 2 switches can use IGMP snooping to constrain the flooding of multicast traffic by dynamically configuring Layer 2 interfaces so that multicast traffic is forwarded to only those interfaces associated with IP multicast devices. As the name implies, IGMP snooping requires the LAN switch to snoop on the IGMP transmissions between the host and the router and to keep track of multicast groups and member ports. When the switch receives an IGMP report from a host for a particular multicast group, the switch adds the host port number to the forwarding table entry; when it receives an IGMP Leave Group message from a host, it removes the host port from the table entry. It also periodically deletes entries if it does not receive IGMP membership reports from the multicast clients. For more information on this feature, see http://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst3750x_3560x/software/release/15-2_1_e/configuration/guide/scg3750x/swigmp.html.

    Power over Ethernet (Plus)The Cisco NIM-ES2-8-P supports POE (802.3af) and POE+(802.3at) on all its 8 ports. PoE provides up to 15.4 Watts of power, and PoE+ provides up to 30 Watts of power. By using PoE, you do not need to supply connected PoE- enabled devices with wall power. This eliminates the cost for additional electrical cabling that would otherwise be necessary for connected devices.
